Purpose/Objectives: Teach student how to implement randomness into their code to make their code simulate real life situations.

In this lesson students will learn:

  • How to import random to python
  • How to use random with a list or number range
  • How to code randomness in everyday scenarios

ADD YOUR ADDITIONAL NOTES HERE:

  • every number in the list has an equal chance of occuring
  • rng topics - dice, stats, cryptography

What are Random Values?

Random Values are a number generated using a large set of numbers and a mathematical algorithm which gives equal probability to all number occuring

Each Result from randomization is equally likely to occur Using random number generation in a program means each execution may produce a different result

What are Examples of Random outputs in the world? Add a few you can think of.

  • Ex: Marbles
  • dice
  • stats
  • cryptography

Why do we need Random Values for code? Sometimes, we need to have random outcomes of a certain scenario.

Random values can be used in coding: 

import random
random_number = random.randint(1,100)
print(random_number)

16

def randomlist():
    list = ["apple", "banana", "cherry", "blueberry"]
    element = random.choice(list)
    print(element)
randomlist()

blueberry

Real Life Examples: Dice Roll

import random
for i in range(3):
    roll = random.randint(1,6)
    print("Roll " + str(i + 1) + ":" + str(roll))

Roll 1:1
Roll 2:2
Roll 3:3

Challenge #1

Write a function that will a simulate a coinflip and print the output

def coinflip():
    return "heads" if random.randint(1,2) == 1 else "tails"

print(coinflip())

tails

EXTRA: Create a function that will randomly select 5 playing Cards and check if the 5 cards are a Royal Flush

Homework

Given a random decimal number convert it into binary as Extra convert it to hexidecimal as well.
